05:29 AM Ruby Revision e064d0d9 (git): [ruby/rubygems] Raise error when gem contains capital letters

The problem is described in https://github.com/rubygems/rubygems/issues/5431
The guide ( https://guides.rubygems.org/name-your-gem/ ) says
> DON’T USE UPPERCASE LETTERS
so `bundle gem` command should respect it.

02:36 AM Ruby Revision 189bb64a (git): [ci-skip] Shorter example for `Module#instance_method`

The previous example code was too complex and includes extra logics
that's not relevant to its main usage: `bind`.
The new example code focuses on `bind_call` so that readers can
understand how it works more easily. okuramasafumi (Masafumi OKURA)

11:14 PM Ruby Revision 895f2c21 (git): [ruby/rdoc] lint: Remove unreachable code

(https://github.com/ruby/rdoc/pull/1137)
This is an attempt to utilize RuboCop further.
RuboCop was added in https://github.com/ruby/rdoc/commit/9262fdd43a3a
but only a few rules have been enabled.
I believe we can utilize RuboCop more ... okuramasafumi (Masafumi OKURA)

10:26 AM Ruby Revision 511925f9 (git): [ci-skip] Fix doc for `refinements`

The current doc is partially wrong since `refinements` method
returns an array of `Refinement` class, not `Module`.
I'm not sure if it's right to link to `Refinement`, but it has
some documentation so it should be useful.

03:43 PM Ruby Feature #16142: Implement code_range in Proc and Method

Hi I noticed we didn't get any conclusion on this topic.
I agree that method name should be something different. It follows the Matz's question: "What do we need from the method? line numbers? offset? whatever?

09:18 AM Ruby Feature #16137: Add === to UnboundMethod

Now that we have had pattern match for a while, I agree with Eregon, we can utilize it more rather than adding new methods.
I cannot change its status so I hope someone will do so instead of me. okuramasafumi (Masafumi OKURA)

12:35 PM Ruby Revision 18f218d6 (git): Add some test cases to Data test

I noticed that `deconstruct` and `hash` don't have enough coverage.
The behavior of `hash` is documented so I copied it. okuramasafumi (Masafumi OKURA)
